ABSTRACT:
A bushing including a tip plate having an orifice region including orifices to permit flow of a molten fiberizable material therethrough; a reservoir for supplying molten fiberizable material to the orifices; and a substantially planar perforated plate positioned within the reservoir generally parallel to and substantially coextensive with the orifice region of the tip plate, the perforated plate including a central region and a peripheral region surrounding the central region, each of the central region and the peripheral region of the perforated plate having a plurality of openings to permit flow of molten fiberizable material therethrough, wherein average head loss of molten material flowing through the central region of the perforated plate is greater than average head loss of molten material flowing through the peripheral region of the perforated plate.
